A very good morning boys

Thank you for logging in

Today we shall be starting our 3rd chapter in Indian Economiv Development which is the 9th unit in our book.

ENVIRONMENT : It refers to the sum total of external forces surrounding us. 

                                   It includes all the biotic elements (birds,animals, plants,etc) as well as                                             abiotic( non-living) elements such as air, water sun, land, mountain, etc)

Functions of Environment

Environment performs the following four important functions.

1.  Supplies Resources for Production: Environmental resources ( such as minerals, wood,water, soilamd others which are available to us as a free gift of nature) are used as inputs in production. Environment provides renewable and non renewable resources.

Renewable resources - are those which can be used without the possibility of the resources becoming depleted or exhausted.Trees, Fishes etc.

NonRenewable resources - are those which get exhausted with their constant use. ex coal , petroleum, oil gas,etc

2.  Sustains Life : Some basic necessities of life ( sun, water,soil and air) are part of environment. Different kinds of plants and trees, birds, animals, etc. survive and grow only in their natural environment. so environment sustains life by providing these. 

3. Absorbs or Accimilates wastes : The process of production and consumption activities generates a lot of wastage, which is absorbed by the environment.

4. Provides Aesthetic Services : Environment includes land, forest, water bodies, rainfall,etc. People enjoy surroundings ( like that of hill stations) which help in improving quality of life.

However , environment is able to function these above mentioned functions only within its carrying capacity.

CARRYING CAPACITY : means the ability of the environment to absorb waste generated during the process of development.

If it does not happen , then environment will fail to perform its crucial functions leading to a situation referred to as " ENVIRONMENTAL CRISIS"
